SPECIFICATION fomnng part of Letters Patent No. 686,200, dated November5, 1901.

Application filed April 25, 1901. Serial No. 57,683. (No model.)

` tralia, have. inventeda certain new and useful Improved Wind-Motor, ofwhich the following is a specification.

This invention relates to an improved windmotor from which more powercan be obtained than from those hitherto in use and which can beconstructed at much less cost.

According to this invention a horizontal shaft revolves in bearings in arotatable U standard or frame on the top of the tower. The said shaftcarries sails or vanes of peculiar construction in that they arecomposed of two semicircnlar metal sheets (preferably of plain orcorrugated galvanized iron orsteel) secured across the shaft at an angleof about forty-five degrees and at right angles to each other. The sailsare braced together and `form an ellipse when viewed from eitherside orfrom either end. From the main shaft is driven a counter-shaft, havingbearings in the said U -standard for reciprocating the pitman-rod. y

In order that the invention may be clearly understood, reference willnow be made to the accompanying drawings, in which-- Figure l is a frontand Fig. 2 a side elevation, and Fig. 3 a plan, illustrating the`improved wind-motor, while Fig. 4 is a plan of one of the sails. Fig. 5is a detail in elevation, on an enlarged scale, showing the manner ofsecuring the sails to the ties.

Portions of some of the figures have been shown broken away for the sakeof clearness.

The same reference -letters indicate the same or corresponding parts.

A is a U-shaped standard or frame carrying the horizontal shaft A' inthe bearings A2.

B B are the semicircular sails or vanes secured across the shaft at anangle of about forty-ve degrees, each sail Vbeing at right angles to theother.

C C' are sprocket-wheels on the shaft A and countenshaft D,respectively, geared together by the chain C2. The speed of thecountershaft may be varied by changing the size of the sprocket-wheels.

D' D' are bearings for the shaft D.

D2 is a crank-disk carrying the arm or crank pin D3 for reciprocatingthe pitman-rod E.

F is a cast-iron sleeve-pipe, having ballbearings at F' (not shown)between its flange and that of the pivot of the U-frame.

G is a Babbitt or other suitable metal bearing, and H a metal capholding the top of the tower rigidly together.

J is the guiding and regulating vane.

K K are lubricating-cups.

L L are ties bracing the sails together.

The somicircular vanes or sails B have rounded notches, as B', centrallyof their straight edges to receive the shaft A' substantially at themiddle of the latter, While the opposite ends of the vanes are fastenedby screws, as L', to the outer ends of the oppo sitelydisposed arms-ofthe ties L, the hubs' of which are fastened to said shaft.

In operation the wind strikes the surface of the sails B, and the shaftA being rotated drives through the gear-wheels C C' the counter-shaftD', by means of which the pitmanrod E is reciprocated. The sails arekept to the wind by the U-frame being pivoted off the center, as shownclearly in Figs. l and 3.

It will be understood that any number of sails may be employed, thisbeing simply a matter of choice, and that alterations may be made in thedetails without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, ism-- l. In a wind-motor, a horizontal shaftand a pair of semicircular sails secured at their inner straight edgesdirectly to said shaft and substantially midway of the length of suchedges, said sails being set approximately at right angles to each other.I

2. In a wind-motor, a horizontal shaft and a pair of semicircular sailssecured at their inner straight edges directly to said shaft andsubstantially midway of the length of such edges, said sails being setapproximately at right angles to each other combined with a rotaryU-shaped standard the branches of which support the opposite ends ofsaid shaft.

3. In a wind-motor, a horizontal shaft and a pair of semicircular sailssecured at their inner straight edges directly to said shaft andsubstantially midway of the length of such Io edges, said sails beingset approximately at right angles to each other combined with a rotaryU-shaped standard the branches of which support the opposite ends ofsaid shaft a second shaft also supported by said standard and drivingconnections between said 15 shafts.
